Numpy geomspace gives error


First of all, thanks for making Python even more accessible in making simple web app :smiley:
So, when exporting my code into streamlit, i hit the wall when I implement np.geomspace.

ctab_many = np.geomspace(ctab[0],ctab[-1],num=200)

UFuncTypeError: ufunc 'sign' did not contain a loop with signature matching types dtype('<U32') -> dtype('<U32')

The traceback:

File "...\", line 323, in main
    ctab_many = np.geomspace(ctab[0],ctab[-1],num=200)
File "<__array_function__ internals>", line 5, in geomspace
File "...\", line 417, in geomspace
    both_negative = (_nx.sign(start) == -1) & (_nx.sign(stop) == -1)

This works just fine in my JupyterNotebook. Maybe some people know or experience the same thing?
Thank you!
